Question

What mass of each element is present in 2.5 moles of Magnesium Sulphate..​

Answer 1

Answer:

Explanation:

MgSO4  molecule contains

1 mole Mg atoms

1 mole S atoms

4 moles O atoms

so 2.5 mole MgSO4 contains

2.5 mole Mg

2.5 mole S

10 mole O

so mass of each element is

Mg  2.5 x 24 = 60 g

S     2.5 x 32 = 80 g

0     10 x 16  = 160 g

Answer 2

Explanation:

MgSO4 molecule contains

1 mole Mg atoms

1 mole S atoms

4 moles O atoms

so 2.5 mole MgSO4 contains

2.5 mole Mg

2.5 mole S

10 mole O

so mass of each element is

Mg 2.5 x 24 = 60 g

S = 2.5 x 32 = 80 g

O = 10 x 16 = 160 g
